ABSTRACT The purpose of this work is to investigate the friction factor for slurries of particles with density close to that of water. The use of particles with density close to that of ice aims to get explanations of new generation of liquid-solid coolant in adiabatic conditions. The solid particles are 3mmdiameter polypropylene sphere, of density 869 kg/m. The test section consists of horizon...

The diameter distribution of savanna tree populations is a valuable indicator health because changes in the number and size trees can signal shift from to grassland or forest. Savanna distributions have traditionally been monitored with forestry techniques, where stem at breast height (DBH) measured field within defined sub-hectare plots. However, spatial scale these plots often misaligned vari...

We performed extensive Monte Carlo simulations of the irreversible adsorption of polydispersed disks inside the cells of a patterned substrate. The model captures relevant features of the irreversible adsorption of spherical colloidal particles on patterned substrates. The pattern consists of (equal) square cells, where adsorption can take place, centered at the vertices of a square lattice. Tw...

In conformity with programming to harvest from virgin resources of Myctophids (Benthosema pterotum) in the Oman Sea (Iranian waters), a series of research cruises and trial fishings were carried out from 1992 to 1998. Assessment of B. pterotum stocks was carried out using the data obtained from a series of seven cruises conducted by R/V Ferdows1 in the Iranian waters using modern scientific ech...
